It doesn't really dispute it, though. Lithium-ion has seen a lot of improvement, yes, because it's already a giant industry; other battery chemistries have a hard time breaking through because they require entirely different processes to manufacture.
I'm still rooting for it, but it's not really the same thing.

    This too is false, great progress has been made on for instance solid state batteries.

    Some progress is being made, but it hasn't seen large-scale adoption yet. Which is the point, as I read it.

    It takes time to scale up production, CATL is already building factories for it:

    On April 21, 2025, CATL unveiled three groundbreaking EV battery products at its inaugural Super Tech Day: The Freevoy Dual-Power Battery, Naxtra - the world's first mass produced sodium-ion battery

    The "progress" is typical industry bullshit. See the absolute bullshit around the Donut SS battery.

    Remember when Musk invented a battery with 30% better capacity? It was a 30% bigger battery.

    SS batteries require manufacturing facilities with clean rooms on the order of chip fabs. You may see these in 2027, but only in expensive cars.

    You can't buy anything with solid state batteries yet, and when you can, they will cost a fortune.

    Uhh you know you can buy an external mag safe battery bank with a solid state battery for like 45 bucks on amazon as well as the big generator ones as well?

    I agree that cost isn't amazing. You are essentially getting about half the capacity per dollar spent to a standard battery device but also these are in fact more stable for temp swings and damage. Soo... consumer available and not a fortune just need to have justification for it.
